9FGL6251AP302NDGI8

Overview

The 9FGL6251AP302NDGI8 is a clock generator and buffer from the Renesas 9FGL6251 series, designed for PCIe applications. It features two differential LP-HCSL outputs with 85Ω output impedance and integrated terminations. The device supports Common Clock (CC) and Separate Reference Independent Spread (SRIS) architectures, defaulting to -0.5% Spread Spectrum Clocking (SSC). It accepts 25MHz or 33.33MHz reference inputs and operates on a 3.3V supply voltage.

Feature Summary

• Two 100MHz Low-power HCSL (LP-HCSL) outputs with 85Ω impedance
• Integrated terminations on DIF outputs eliminate external resistors
• SMBus-selectable -0.25% SSC; SRIS/CC architectures default to -0.5% SSC
• Supports 25MHz or 33 1/3MHz reference clock input

Applications

• Single and dual-ported nVME SSDs
• PCIe master/slave clocking
• Clock multiplexing applications

Procurement Notes

Verify the specific suffix 'NDGI8' against official Renesas documentation to confirm package type and moisture sensitivity level. Factory packaging quantity is typically 2500 units per reel. Confirm RoHS compliance status via the manufacturer's datasheet before procurement.

Selection Notes

Select this component for designs requiring 85Ω output impedance and integrated termination resistors. Ensure the system architecture supports SRIS or CC modes with -0.5% SSC defaults. Verify compatibility with 25MHz or 33.33MHz reference clocks and 3.3V operating voltage requirements.
